. 1 l arme-GEAR.

To qll whom it may concern: B e it known that I FREDERICK Y BLCK- LEY, citizen-of the United States, residing at Hazleton, in the county of Luzerne 'and 5 State of Pennsylvania, have invented certain new and useful Improvements in Running-Gears, of which the following is a speciication.

Vehicle running gear embody holsters 1'0 which either support the load direct-ly or are attached to a bed or body designed to receive .the load. Y'

vThe primary object of this invention is to provide a bolster of `novel formation; to

combine therewith a cap which is 'adapted to be-}.\osi ti\-'ely connected with the bed or hottom of the body and having sliding and yielding connection with vthe bolster; and to improve the general construction in a man ner substantially as indicated hereinafter and shown in the accompanying drawings,

.v in which:

n Figure l is a top plan view of vehicle rung ning gear embodying the invention. Fig." 2 is a section on the line x-x of Fig. 1 showing the )arts on a larger scale. Fig. 3 is a tentral ongitudinal section on the line 3-3 of Fig. 1, the coupling means being in full exlcept at the frontend. Fig. 4 isa detail perspective view of the vupper member of the front bolster. Fig. 5 is a detail perspective view of the lower member of the. iront bolster. Fig. 6 is a transverse section on the line Y6 6 of Fig. 1.

Corresponding and like parts are referred' to in the-following description and indicated in all the views of the drawings by the saine reference characters.

As shown most clearly in Fig. 2, the. rear 'l0 bolster is a one-piece structure, whereas the front bolster is composed of two members as illustrated most clearly in Figs. 4 and 5. The u' iper and lowerportions of the bolster are su. stantially the same whether the bolster is of a single or a two-part formation. The upper member or portion of the bolster is hollow or channeled toreccive a seriesof Y springsl and spring guides and bullets. The lower portion or member of the bolster is 5q` channeled or formed near opposite ends`with spaced' portions to embraceopposite sides of the axle 2, thereby preventing forward or rearward movement or dlsplacement of the Specjicationof Letters Patent.

l their lower ends' being connected by means i of a yoke 4 which ext-ends beneath the axle and bolster. Positive interlocking means is l provided between the yoke 4 and the axle to l prevent any longitudinal movement of the l axle. Said locking means consists of a pro ject-ion 5 which may'extend either from the i plate 4 or theaxle 2 as indicated in Fig. 3 and l enter an opening or depressionv in either the l' plate or the axle. The couplingmeans are i interposed betweeny the holsters and are of suchfconstruction and relative arrangement l as to admit of the holsters having a limited g relative angular movement, whereby the fore and hind gears may adapt themselves to varyingconditions in the surface of the road without straining the connections to a degree 1 ning gear as a whole. A fifth wheel is interposed between the membels of the front bolstel', the complemental parts of the fifth v'heel being formed with orvattached to the respective members. I'nasmuchas the up- )erportion or member of the holsters is of like construction, a detail description will suflice for a clear understanding of both. A series of studs 6 project upward from the botf upper side ofthe bolster and are recessed to receive rubber bumpers 7. ceive the lower ends of the coil springs 1 and hold theln inA place. Rollers S are provided at opposite ends of the bolster and are de- -signe to sustain the end thrustv of the bolstercap 9. To prevent rattling of the rollers 8, springs 1t) exert. a pressure thereon and are secured to the bolster.

and sidesand is formed of sheet metal and closes the. top side and ends of the space or channel formed in the upper side of the bolster. The springs 1 hold the cap elevated and' support the load. To reduce the friction between the sides of the cap and the sidesl of the bolster, rollers 11 are provided l and are mounted upon the cap and project lthrough openings formed in the sides thereof lso as to engage the sides of the bolster. The rollers 11 are protected by means of housings 12 which are of bracket formation and are fastened to opposite sides ofthe cap, and have jouter flanges at their upper ends to receive the fastenings by means of which the cap is to cripple or impairthe efiiciency of the run tom of the channel or space formed intheV The studs 6' re-j The bolster cap Q'is closed at its top endsl ioo iarts'.' The lower portion or member of the g secured to the bed or bottom of the wagon 110 55 lmlster iscli pcd at its ends-to the aslefthe i body. The pins upon which 'the rollers 11mm-WWW' clips being itted in grooves or seats 3 and are mounted are supported at their ends in .,the sides of the housings 12. .constructed of' sheet metal, preferably steel,`

- 'is adapted vto have its sides comt'iresse'd more and the sides of the bolster asalsoto-'ins'ure a'close fit between the cap and bolster. To

secure the cap to the bolster and to provide"v for compressing the sides thereof, bolts. 13

are employed, the same passing through openings formed 1n opposlte sides of the cap A in coincident 'relation and through vertical 'slots 14 formed inthe bolster.

are mounted upon the bolts 13 so as .to reduce bolts 13 may be tightened, therebyl maintaining contact of said rollers with the sides of the. bolster.A

W'hile it is preferred to have the caps` )ositively connected yto the bed or bottom oi the vehicle, it is notessential that such connection be resorted to because some varieties of wagons, and particularlyv those constructed to receive the load directly upon the bolster, do not empioj,v either a bed or a body, and 1n adapting the invention for this class of wagons, the housings 12 will be'modiiiedsso as to inclose theollers 11 and withoutea view of connection to anv superstructure. The rollers 11, besides minimizing the friction between tl'ie cap and the bolster, also sustain Y the forward and backward thrusts from loads in goingup and down grades.

Having thus described the invent-ion, what is claimed as new is:

1. In combination, a bolster having the upper port-ion thereof channeled, guide rollers journaled Within the channeled portlon of the bolster at opposite ends thereof, a 4cap fitting loosely over the channeled portion of the bolster the ends 0f the cfa-P engaging the 'I The-'cap being inthe sides thereof, housings the friction between said boltsl and the'sides of the slots' 14. As the rollers 11 wear, the

g before mentioned guide rollers, and springs i interposed between the bolster and can and inclosed within the cap.- or lessto allow for wear between the rollers 2.'. In combination, a bolster, acapfitting .loosely over the bolster and having openings in ,y the sides thereof, `vielding means interposed between the bolster and cap, and guide roll'- ers mounted upon the exterior of the cap and g operating through the o enings in the .sides Q thereof to engagethe bo ster.

3. In combination, a bolster, a cap itting Rollers 15 I loosely .over the bolster and h avinfy o lungs appe to the exterior. of the'cap, guide rollers journaled within the housings and operating through the openings in the sides of the cap to engage the bolster, and a yielding means interposed between the bolster and cap.'

4. In combination, a bolster having verand having a depression in its upper side, and projections extended upward from the bottom of said depression, a cap embracing the ends and sides of the upper portion of the bolster, bumpers fittedv inthe upper ends of said projections, springs interposed between 6o tical slotsextended through opposite sides.

the cap and bolster and iitted to said projections, bolts passed through vthe vertical slots of the bolster and connecting oppo site sides of the cap,v sleeves mounted upon the said bolts, rollers mounted upon the terminal portions of the holsters and adapted to engage with the ends of the cap', and spi-ings fast Vat one end to the bolster and bearing against said rollers.

In testimony whereof I affix my signature in presence of two Witnesses.
